Serum immunoglobulin (Ig) A, IgG, and IgM anti-MAA and serum IgG antibacterial antibody concentrations were quantified by enzyme-linked immunosorbent assay (ELISA). Analyses utilized simple linear regression and multivariable adjusted models.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>No significant associations of periodontal clinical measures with serum anti-MAA were found. Moderate (<i>p </i>= 0.038 and <i>p </i>= 0.036, respectively) and high ABL (<i>p </i>= 0.012 and <i>p </i>= 0.014, respectively) in RA cases (but not in OA) were positively associated with IgG and IgM anti-MAA. Anti-<i>P. gingivalis</i> and anti-<i>P. intermedia</i> antibody concentrations were positively associated with IgA (<i>p </i>= 0.001 for both), IgG (<i>p </i>= 0.007 and <i>p </i>= 0.034, respectively), and IgM anti-MAA antibody concentrations (<i>p</i> &lt; 0.001 and <i>p </i>= 0.020, respectively), while anti-<i>F. nucleatum</i> was positively associated with IgG anti-MAA (<i>p </i>= 0.042), findings that were similar across groups.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>A positive association was demonstrated between ABL and serum IgG and IgM anti-MAA antibody concentrations that was unique to RA and not observed in OA. Serum anti-<i>P. gingivalis</i>, anti-<i>P. intermedia</i>, and anti-<i>F. nucleatum</i> antibody concentrations displayed significant associations with anti-MAA antibody in both groups. These findings suggest MAA may play a role in the interrelationship between the periodontium and RA.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16716,"journal":{"name":"Journal of periodontology","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/JPER.23-0604","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140904295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
